Eagle Behavior and Risk Modeling for Wind Energy workshop¶

Stochastic Soaring Raptor Simulator (SSRS)¶

Demonstration¶

Github repository: https://github.com/NREL/SSRS

Journal publication: Stochastic agent-based model for predicting turbine-scale raptor movements during updraft-subsidized directional flights. Ecological Modelling, April 2022. link

Features:

  • Easy to use tool for predicting conflict between likely golden eagle routes and operational/planned wind turbines
  • Applicable to any region in the continental US since it only uses publicly available data sources
    • NREL's Wind ToolKit (WTK) for extracting atmospheric conditions (currently 2007-2014)
    • USGS's Wind Turbine Database (USWTB) for extracting turbine locations (updated monthly)
    • USGS's 3DEP elevation map for extracting terrain features at high resolutions (upto 10 m)
  • Captures uncertainty in atmospheric conditions, eagle decision-making, and starting/entry location

Limitations:

  • Simulates only horizontal (2D) movements
  • Does not explicitly consider flight modes such as flapping, stooping, and low-altitude thermal soaring
  • Does not distinguish between resident and migrating eagles
  • Ignores turbine avoidance behavior of eagles
